- OBJECTIVE: To test whether feedback and discussion of ergonomic and psychosocial working-environment data during one short session with individual, groups or supervisors of white-collar computer workers had an effect on activity to modify workplace design, working technique and psychosocial aspects of work. METHODS: A total of 36 workgroups from nine organizations representing different trades was randomized (stratified for organization) to three feedback conditions or control with no feedback. Data were collected 1 month before and 6 months after feedback sessions. The effects studied were: (1) change in the proportion of workgroup members who reported any modification regarding workplace design or working technique; (2) change in the proportion of workgroup members who reported any modification regarding psychosocial aspects; (3) average number of modification types regarding workplace design or working technique per individual in a workgroup; (4) average number of modification types regarding psychosocial aspects per individual in a workgroup. RESULTS: All feedback conditions differed positively from controls regarding change in the proportion of workgroup members who reported any modification in workplace design or working technique. No such effect was found for psychosocial aspects. For change in average number of psychosocial modification types per individual in a workgroup an effect was observed for feedback to supervisors. No intervention effect was observed for the average number of modifications in workplace design or working technique per individual in a workgroup. CONCLUSION: Feedback and discussion of ergonomic and psychosocial working-environment data during one short session with individual, groups or supervisors of white-collar computer workers may have a positive effect on how many people in a workgroup modify (or have modifications done regarding) workplace design and working technique. Feedback to supervisors may have an effect on the average number of psychosocial modification types per individual in a workgroup. Feedback to group supervisors appeared to be the most cost-effective variant.

- OBJECTIVES: Despite extensive research on turnover among nursing personnel very little is known about the impact of physical workload and health on leaving. The aim of this study was to find predictors for leaving nursing care with special reference to physical working conditions and musculoskeletal problems. METHODS: This study is based on longitudinal data from a survey of nursing personnel who were employed at various county hospitals in Sweden from 1992-95. A self administrated follow up questionnaire was used to identify their present position in the labour market. The response rate was 73% (n = 1095). RESULTS: The results showed that nursing personnel reporting musculoskeletal problems of the neck/shoulder or knees and those who had limited use of transfer devices were more likely to leave nursing care. CONCLUSIONS: The study highlights the importance of taking musculoskeletal problems and use of transfer devices into consideration in order to retain nursing personnel.

- The aim of the present study was to assess the incidence and identify possible risk factors for self-reported reduced productivity owing to musculoskeletal symptoms among computer users. DESIGN: a cohort study with a baseline questionnaire and monthly follow ups during 10 months. METHODS: the study base consisted of 1,283 computer users, 636 men and 896 women. Ergonomists observed workstation characteristics before entering the cohort. Cases were defined as subjects reporting reduced productivity or reporting being on sick leave owing to musculoskeletal symptoms. RESULTS: women had approximately two times the incidence of self-reported reduced productivity owing to symptoms in the neck, shoulder and in the forearm/hand than men. There was no difference in gender for the incidence of self-reported reduced productivity owing to back symptoms. Working overtime and job demands were risk factors for self-reported reduced productivity owing to neck and back symptoms. Physical exercise fewer than 8 times the last month was a risk factor for self-reported reduced productivity owing to neck, shoulder and forearm/hand symptoms. Computer mouse use for more than 0.5 h/day was a risk factor for self-reported reduced productivity owing to shoulder and forearm/hand symptoms. CONCLUSIONS: risk factors for self-reported reduced productivity owing to musculoskeletal symptoms included life style factors, such as overweight and low physical exercise, occupational factors, such as overtime, job demands and computer mouse operating time.

- The aim of the present study was to evaluate the concordance (agreement) between VDU-users' ratings of comfort and ergonomists' observations of workplace layout, and the concordance between VDU-users' ratings of perceived exertion and ergonomists' observations of working postures during VDU-work. The study population consisted of 853 symptom free subjects. Data on perceived comfort in different dimensions and data regarding perceived exertion in different body locations were collected by means of a questionnaire. Data concerning workplace layout and working postures were collected with an observation protocol, by an ergonomist. Concordance between ratings of comfort and observations of workplace layout was reasonably good for the chair and the keyboard (0.60, 0.58) and good regarding the screen and the input device (0.72, 0.61). Concordance between ratings of perceived exertion and observations of working postures indicated good agreement (0.63-0.77) for all measured body locations (neck, shoulder, wrist and trunk). In conclusion ratings of comfort and perceived exertion could be used as cost-efficient and user-friendly methods for practitioners to identify high exposure to poor workplace layout and poor working postures.

- Objectives: Computer use, neck and upper-extremity symptoms, headache, and eyestrain were studied in upper secondary school students. Methods: A questionnaire was completed by 1575 female and 1251 male students. Associations between computer use and health problems were analyzed by calculating the prevalence ratios for the health variables, considering computer use for >14-56 or >56 hours/week as compared with ≤14 hours/week (reference). Health problems were defined as aches or pain or other trouble at least three days in the preceding month. Results: Computer use (median) was reported to be 31 hours/week by the male students and 19 hours/week by the females. Most computer use (about 90%) took place outside school (eg, for entertainment). Headache was reported by 51% and 24%, and neck or shoulder symptoms by 31% and 15%, of the females and males, respectively. More than 50% of the females with health complaints indicated that their problems had disturbed their sleep, and they used painkillers to handle them. Between 10% and 43% experienced their health complaints as being related to computer use. For those using computers >56 hours/week, the prevalence ratios were significantly increased for neck or shoulder symptoms among both the females and the males, and for eyestrain and forearm symptoms among the females. Exposure-response relationships were indicated for the aforementioned associations. Approximately two-thirds of the students reported that they had not received any information in school about appropriate workplace layout and techniques for computer work. Conclusions: Despite their young age, the students were not protected from computer-related health complaints. Therefore, providing adolescents with information about proper computer ergonomics may help prevent such health problem.

- BACKGROUND: Symptoms from the eyes are common among computer users. Knowledge is scarce about these problems, however. OBJECTIVES: The aim was to study risk-factors, incidence and persistence of eye-symptoms among professionally active computer users. METHODS: This was a questionnaire based prospective study where 1283 males and females from different professions and companies answered a baseline questionnaire about individual factors and working conditions, e.g. duration of daily computer work, comfort of screen work, psychosocial factors. Subjects were at baseline and 10 follow-ups asked about the number of days with eye-symptoms during the preceding month. RESULTS: The incidence-rate of symptoms persisting minimum three days was 0.38/ person-year. A multivariate Hazard-ratio model showed significant associations with extended continuous computer work, tasks with high demands on eye-hand coordination, low level of control, visual discomfort, female sex and nicotine use. Eye-symptoms at baseline was a strong risk factor for new symptoms. CONCLUSION: The incidence of eye-symptoms among professional computer users is high and related to both individual and work-related factors. The organization of computer work should secure frequent breaks from near-work at the computer screen. The severity of vision-related problems could in field studies be quantified by asking for the persistence of symptoms.
